Problem add new plant in 2LIS_03_BX, 2LIS_03_BF - Archived data

Hi Experts,

We are in big truble with our Inventory Flow in our BW system.

When we started we made a BX setup with selection on plant (0003-0008) and also our BF setup (and also todays delta) has a selection on Plant (0003-0008).

We now wants to add another plant 0010 to the delta. We have noticed that it is not possible just to add the plant to the 2LIS_03_BF Delta info package and in seems fair since the initialization regards Plant 0003-0008.

In our R/3 system (the source system for our BW system) we have archived data that concern Inventory data (material document etc) and as we understand it is not possible to make a new Initialisation that will give us a correct inventory delta. Or do You know if it possible to include archived data in the initialization of 2LIS_03_BF and 2LIS_03_UM?

We are not sure how this extractors works; The BX seems to be like a todaystatus and the BF and UM u201Ccalculates backwordsu201D in some way to get the correct figures; IS THIS CORRECT?

Does anyone have any ideas how to add a Plant under this circumstances; Selection on Plant when start of Delta, Want to add new plant to the delta, Data regarding material documents etc archived in the Source system.

Regards,

Kerstin
