You map an IRD by updating the data set information using the manual mapping dialogs only.
This displays the screen in Figure 1.
--------------------- CICS VT: Update data set mapping ------------------------- Command ===> __________________________________________________________________ DIM name ===> APPLCTL_ Field build user exit name ===> ________ If selected, you must build all fields for the data set with the specified exit I/R/D user exit name ===> MULTIRD_ I/R/D user exit processing order ===> A (B=Before,A=After,' '=Both) I/R/D user exit language ===> L (A=Assembler,L=LE enabled) DIM ready to be generated ===> Y Enter=Update PF3=Exit
The IRD MULTIRD is written in an LE/370 language and is invoked after the DDM has processed the SQL INSERT/ DELETE/UPDATE call. (The field value for I/R/D user exit processing order is A.)
When you map an IRD, the exit processing order is the main mapping option to consider.
