It looks like the client created an include member with MOVE statement.
I initially tested MOVE statement does not work with CA InterTest Batch.
CA InterTest Batch has it's own SET command to use in order to set the value of data field.
I create separate include member and changed as follow:
From original client's file:
MOVE 681952 TO RLL03261-EMP-USER-ID
MOVE 0043 TO RLL03261-FORM-TYPE-ID
MOVE 'RR' TO RLL03261-INV-ADJMT-ACTN-CD
SET RLL03261-EMP-USER-ID = 681952
SET RLL03261-FORM-TYPE-ID = 0043
SET RLL03261-INV-ADJMT-ACTN-CD = 'RR'
And testing INCLUDE command works with SET command modification.
