Batch Control Source Field
Mandatory.
Specify from 1 to 4 fields in this file (i.e. the file definition currently selected) that are to be accumulated into the "batch control file" identified by the Batch Control File Name.
At least one pair of fields (source and target) is required.
Rules
- All fields nominated must be defined in this file.
- 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.
