We use FIFO valuation. We added some lines in table MYMP1 using MR34.
It turns out they are lost when running a new extract on the period using MRF3.
Any idea on how to keep these lines added manually ?
I tried to tick the MYMP1-XTERN field (debug way) : it works and the new lines are kept when running a new extract. Do you know how to get this field ticked a standard way ?
I did not find any exit nor badi on these programs that helps.
Thanks for your help.
