Seems this is in fact an SAP issue. I copied all the FM's into Z based FM's,
Took this line of code:
using value(i_matnr) like csap_mbom-matnr
and changed it to this:
using i_matnr
And got past the errors.
However, the Opening of the BOM still is not happening. Trying to do heavy debugging to figure out why it is failing. SY-SUBRC is returning a value of 1. Just not sure why yet.
I can't believe that I am the only one having this issue.
Is there any way to work around using these FM's to modify a BOM?
I would have liked to have done it with an LSMW but we have about 1200 BOM's that have to be updated. Only one item in each of these needs to be updated and the item is not the same item number for each BOM. Could be 0010 on one and 0060 on another. LSMW would not allow me to put the item number in. When doing the recording, if it was on 0060, it would hard code that into the LSMW instead of giving me the option to specifiy from an input file which ITEM_NO to modify.
Anyone else have any ideas? Is there some way more modern than CSAP_MAT_BOM_OPEN?
