a) Use the "subscriptionpack.zip" provided with the CIM under $MQ_COMMON_DIR/standard/misc/ directory. It has document (HowTo_ImportSubscriptionpack.doc) with all the instructions on how to import it into the enterprise.
b) Once the subscription pack is imported it will create a EANUCCSUBSCRIPTIONCATALOG master catalog.
c) Now replace the map file (mpfromcatact26towwre30rfcinv1.xsl) under $MQ_COMMON_DIR/standard/maps/ with the attached map file (mpfromcatact26towwre30rfcinv1_fix.xsl) which is actually modified to send the GTIN, GPC CODE, Target Market only when they are populated
d) After replacing the map file, add a simple new record with GLN populated in the SUPPLIERID attribute with some PRODUCTID and PRODUCTIDEXT
e) Then do a Send message for that record through the record view page.
By doing the above, one can have RFCIN sent by GLN or GTIN or Target market or GPC code.
