In CIDS How do you MERGE 2 INPUT files into 1 OUTPUT File

I person 2 files created from SAP tables, MARD and MSKA, that person the aforesaid format. I request to MERGE these to files into 1 combined file. INPUT1 has 10 records...INPUT2 has 15...my OUTPUT needs to incorporate 25 records. Is casual to bash successful Data Services with the MERGE Transform but successful CIDS I spot nary way.
