red = the stock is not available
yellow - the stock is in average level stock
green = the stock is available
2. What is MRP List and what is the use of it?
Definition of the MRP List
The system creates MRP lists during the planning run
according to how you set the creation indicator. These lists contain the
planning result for the material. The MRP list always displays the stock/requirements
situation at the time of the last planning run and it also provides a work
basis for the MRP controller. Changes that are made after the planning
date are not taken into consideration, so the list is static.
MRP lists are stored in the system until they are either
deleted manually or replaced by new lists from a subsequent planning run.
3. What is the use of Stock Requirement List?
In the stock/requirements list, the most up-to-date stock
and requirements situation is displayed.
The main difference between the MRP list and the stock/requirements
list is that each time the stock/requirements list is called up, the system
selects the various MRP elements and displays the most up-to-date situation.
You thus always see the current availability situation of the material
in the stock/requirements list. Changes that are made after the planning
date are displayed directly, so the list is therefore dynamic.
Stock/requirements lists are not saved in a fixed state
in the system, but are subject to change and only exist in the working
memory.
Comparison
The screen layout of both lists is basically the same.
The system automatically runs the rescheduling check
directly when both lists are created and puts forward rescheduling proposals.
The number of exception messages displayed in each list
is roughly the same. The only difference lies in the fact that, due to
the nature of the list, no exception messages can occur for newly planned
MRP elements in the stock/requirements list.
Directly after the planning run, both lists contain the
same information. As soon as a change relevant to MRP is made, the system
updates the information in the stock/requirements list.
As stock/requirements lists are subject to change, they
cannot be set with a processing indicator.
4. What is MRP controller Means?
The MRP controller is a person or a group of persons responsible
for monitoring material availability. You can use the number entered here,
for example, to select the planning results per MRP conroller.
Every material that is relevant to the planning run must
be assigned an MRP controller number in the material master record.
You can also determine a special person for backorder
processing who receives a mail if a goods receipt was posted for a missing
part. You must enter the mail name of this person in the field entitled,
recipient name.
In addition, you can define a person or a group of persons,
who are to informed if you send a mail from the MRP list or stock/requirements
list to the MRP controller for the material displayed.

5. What is MRP group and what is the use of it?
MRP Groups
In this step, you can carry out the total maintenance
of the MRP groups and you can allocate a material type to an MRP group.
The MRP group is an organizational object that can be
used to allocate special control parameters for planning to a group of
materials. You can maintain MRP groups if planning control per plant is
not precise enough for your requirements and you want to allocate certain
material groups different control parameters from the plant parameters.
For this purpose, MRP groups are defined with these specific control parameters
and are assigned to the material in the material master record (MRP 1 screen).
For example, the following control parameters can be
set for the total planning run:
the creation indicator for the plarequisitions, MRP lists,
and so on)
the planning horizon
the consumption mode
The following is valid for total planning and single-item
planning:
for all materials without an MRP group, the system uses
the plant parameters, or the entries in the initial screen of the planning
run
for all materials with an MRP group, the system uses
the parameters recorded in the MRP groupnning run (creation of purchase
6. What is Purpose of Schedule Margin Key?
In this step, you specify the floats for determining the
basic dates of the planned orders. The floats are allocated to the material
via the release period key in the material master record.
Opening period
The opening period represents the number of workdays
that are subtracted from the order start date in order to determine the
order creation date. This time is used by the MRP controller as a float
for converting planned orders into purchase requisitions or into production
orders.
Float before production
The float before production represents the number of
workdays that are planned as a float between the order start date (planned
start date) and the production start date (target start date).
On the one hand, this float is intended to guarantee
that delays in staging a material do not delay the production start. On
the other hand, the production dates can be brought forward by means of
the float to cope with capacity bottlenecks.
Float after production
The float after production should provide a float for
the production process to cope with any disruptions so that there is no
danger that the planned finish date will be exceeded. You plan the float
after production between order finish date (planned finish date) and scheduled
end (target finish date).
Release period
The release period represents the number of workdays
that are subtracted from the order start date in order to determine the
production order release. The release period is only relevant for production
order management.
7. What is opening period?
Opening period
The opening period represents the number of workdays
that are subtracted from the order start date in order to determine the
order creation date. This time is used by the MRP controller as a float
for converting planned orders into purchase requisitions or into production
orders.
8. What is SLA ? Service Level Agreements
Service Level Agreements (SLA) define the attributes for service products (for example, maintenance, Hotline) that have been agreed upon with the customer in service contracts. The SLA confirms different parameters, such as response time, availability time and system availability.
9. What are Basic Dates?
Earliest date for the execution of the production order.
This date takes into account the float before production.
If, on order creation, a planned order exists for the
production order or process order, then the order dates are taken from
the planned order. When scheduling the production order the system tries
to adhere to the order dates (if necessary, with reduction measures).
If it is not possible to adhere to the basic dates and
if the control parameter in Customizing allows the basic dates to be adjusted,
the system adjusts the basic dates of the order during the scheduling run.
If the control parameter in Customizing does not allow
the basic dates to be adjusted, the order keeps the basic dates of the
planned order.
If the production order is created manually, you must
enter at least one order date manually.
The scheduling type determines, which order dates you
must enter.
10. What is planning time fence?
The planning time fence specifies a period within which
no automatic changes are to be made to the master plan.
The planning time fence is maintained in workdays.
11. What is Planning Horizon?
In this step, you define the planning horizon. This planning
horizon specifies the period for the "Net change planning in the planning
horizon".
In this kind of net change planning, only those materials
that have undergone a change that is relevant to MRP within the planning
horizon are included in the planning run. Such materials receive a net
change planning indicator in the planning file.
You make this specification for a plant. You can define
an alternative planning horizon for MRP groups
12. What is Group BOM?
Alphanumeric character string used to uniquely identify
a BOM.
Use
If you assign a "meaningful" number to a BOM group, this
gives you an additional way of accessing the BOM.
The system stores the following under a BOM group:
all the alternatives in a multiple BOM
all the BOMs entered for a variant BOM
13. What is costing? How it is affected the PP?
Determining the material costs of a product.
When you calculate production costs using a quantity
structure, the system automatically determines the BOM and all the BOM
items that are relevant to costing, in order to calculate manufacturing
costs.
14. What is Meaning of Customized Reports?
The report which is not using SAP standard reports.
15. In Project the Customization is comes under Which Phase?
Realization.
16. How you get the Ticket?
After release order,the reservation will provide the ticke to pick production material.
17. What are GAPS? Some Examples?
The GAPS are some issue in blue print that SAP cannot capture or prividing the client bussiness process.
18. What is LSMW?
The LSM Workbench is an SAP System tool that supports
you when copying data from non-SAP.
systems.
19. After Doing Realization How we will check whether it is working or not?
Doing Final preparation to check using the test case from user.
20. What do we do in Realization Phase?
Provide ARICEF, Configuration Documents, integration test, BPP, UAT, Unit Test and implements some SAP notes.
21. How to Move to the Realization Phase?
You must have some blueprints to go in next phase.
22. In LSMW which is most important Step?
