Gross Requirements Planning in Long-Term Planning 
Use
You can carry out gross requirements planning in long-term planning for cost evaluation and budgeting. With this procedure, you only plan the actual requirements quantities without taking available stock, material-specific lot-sizes or scrap into account.
Gross requirements planning is supported by the following functions:
- Use of special lot-sizing procedures for long-term planning
- No calculation of scrap quantities in long-term planning
Prerequisites
You must create a planning scenario for gross requirements planning.
If you select gross long-term planning when creating the planning scenario, the system automatically proposes the appropriate control parameters.
Features
Lot-sizing procedures in long-term planning
In a gross requirements planning scenario in long-term planning, the system always uses either a lot-for-lot or a period lot-sizing procedure for the lot-sizing calculation for all explosion levels, even if other lot-sizing procedures are set in the material master record.
You achieve this by selecting the Use gross lot size field in the planning scenario and by entering either a lot-for-lot order quantity or a period lot-size in the gross lot size field.
In the planning run, all materials selected as "gross lot size" are planned without taking the parameters from the material master record into account.
Long-term planning without scrap
In long-term planning, you can calculate which material requirements and costs could be saved if no scrap were produced in simulative mode.
You do this by setting the Switch off scrap calculation indicator in the planning scenario. This results in the following:
- No assembly scrap is planned in the net requirements calculation.
- Neither component nor operation scrap are not taken into account in the BOM explosion.
