All transactions in MIMS sit in the Master transaction table MSF900 and the detail of transactions sits in linked child tables, eg MSF900_S for inventory issues.
Your requirement to extract issue transactions can be easily programmed without Mincom support using various tools such as: Corvu, RDL, sqlplus, etc and reporting off MSF900_S. You may need to link MSF900_S to other tables if you need to extract descriptions, eg MSF100 for stock item description etc. You need a programmer with some MIMS experience so that they undestand the links between various tables and a bit of how the system works/is designed and its functionality.
