JAP = Jarda´s SAP modul (Jarda comes from Jaroslav )
my bigesst SAP project ever
Production Planning and Detailed Scheduling (PP/DS) or in other words Advanced Planning System (APS)
This module is fully integrated in SAP .
In generally and in details how APS works can be found on the internet
How does it work shortly in this case:
- Step. In the night, after MRP task, starts job=> the all sales order schedules are scanned and built their order net with all the needed components .2. All the production orders are scheduled through their working steps/time and working place.
After the main job is done, one has many options to evaluate the situation in the plant.
View resource group of people (with workers in that group)
Why do I need my own APS system if there is plenty in the marketplace incl. APO from SAP?
I haven´t found one there with features that needed in our firm
Most of them are add-ons, my solutions is in SAP included
I can anytime change the logic of planning to my own
I can skip direct in other SAP transactions
I can use OTP logic (see Goldratt and TOC)
Production orders are not moved in time due to planned logic.
The full coding has over 20.000 lines…..
As example used function modules:
CALL FUNCTION 'MD_SALES_ORDER_STATUS_REPORT' EXPORTING edelet = i_edelet edelkz = c_edelkz edelnr = lv_prevod edelps = i_edelps eplscn = i_plscn availability_check = availability_check no_savety_stock = sicherheitsbestand_mit * no_savety_stock = 'X' " * DATA_IN_MEMORY = ' ' * MEMORY_ID = 'PLHS' * EMATNR = ' ' * EWERKS = ' ' * EBERID = ' ' * EMDPS = nodisp = 'X' i_ignore_mtold = 'X' i_profid = profil_id * I_REP_REFRESH = ' ' * IS_PROFILE = * IT_VBEP_KEYS = no_commit_work = 'X' IMPORTING et_rtree_sel = lt_tree TABLES iioelx = lt_ioel EXCEPTIONS error = 1 OTHERS = 2.
