This is a data modeling question. Some of the Document numbers in BW are not defined as Master Data (example: 0AC_DOC_NO). Are there any internal SAP issues (either in BW, or in BW->R3 data extaction) if we re-defining these documents as Master Data in BW? We would like to add attributes to 0AC_DOC_NO, and use it as Master Data on more than one Infocube. I'm wonding if something like document number range processing in memory, etc, will be adversely affected.
