Batch Control Target Field
Mandatory.
Specify from 1 to 4 fields in the "batch control file" that are to hold the accumulations of the fields from this file.
At least one pair of fields (source and target) is required.
Rules
- All fields nominated must be defined in the file identified in the Batch Control File Name.
- All fields must be numeric.
Warnings
- The checking (and testing) of accumulated field precision is a user responsibility and is not performed by LANSA.
Tips & Techniques
- Note that while LANSA will check that all fields nominated exist in their respective files, and are numeric, it will not check the sizes. Thus it is possible to accumulate a field with 4 decimal positions into a field with no decimal positions. All decimal precision would be lost and the accumulation would probably be meaningless. Likewise a field with 15 significant digits could be accumulated into a field with 1 significant digit. Again the accumulation would almost certainly be meaningless.
