Hi Ignacio,
I think you can use BAdI MD_ADAPT_DISTRIBUTION to adjust the start and
end dates/times for the distribution function.
This is the help document from SAP:
-------------------
You can use this Business Add-In in the component PP-MRP-PE to adjust
the following parameters for the distribution of order/requirement
quantities:
o Start and end date of the distribution
o Valid factory calendar for the distribution
In the standard behavior, the relevant planned order quantities are
distributed between basic start and basic end date or the component
requirement quantities between between earliest and latest requirement
date. In some applications, however, especially in the process industry,
it may be useful to stipulate a distribution interval that is better
geared to the actual production dates here. Thus, for example, you can
stipulate in the BAdI that the production dates determined by the system
in lead-time scheduling are to be used for the quantity distribution.
The following methods are available:
o You can use the ADAPT_ORDER_DATES method to adjust the start and end
date for the distribution of the order quantity (quantity of header
material). The distribution function at the level of the order
header is effective only in the display transactions of material
requirements planning, not for the planning.
o You can use the ADAPT_DEP_REQ_DATES method to adjust the start and
end date for the quantity distribution of the components.
These changes are effective not only in the display transactions of
material requirements planning, but also for the planning.
Best Regards,
Hengky
