Description

In the solution , we have two scripts (web services) . One for retrieving  and other for uploading . Multiple rows of data to be retrieved . Manually edited . Updated. Two scripts are imported . We use "Generate Repeating Section" for the web services to accumulate multiple rows of data .
In 'Field Mapping ' we use existing input and output . As same table has to be used by both the web services . When we retrieve (first script execution) works well . Edit the values . When we update(second script execution) gives following error

Applies To

Composer ; Designer ; Workflow ;

Cause

The second script is not able to read the mapping though provided . (Either with manual mapping or use existing input and output fields).

different Group Names on the two web services (buttons) in the repeating table

Solution

In Field Mapping for both the script , same group name should be provided so two web services use the same fields including "Allow Run" field .
" Allow Run" is not a field of script . Hence it cannot be mapped using manual or use existing , Above approach of same group name will make it happen automatically.

We can resolve this by re-importing one of the scripts and changing the Group Name to the same as the other web service.
