How can I perform the loop function in SAP Integration Suite, managed gateway for spend management and SAP Business Network with Value Variable?

If you tried to perform the loop function with the item Position and it didn't work, you could perform it using the Value Variable as the following steps:

1. Right click on mapping line.
2. Click Target Variable > Add Value Variable.
3. Click on the target sequential field that contains the value we could match with the sourcing one. It could be the field @lineNumber, for example.
4. Repeat step 1 > click Add Source Condition > Select the source sequential field you'd like to match.
5. Click Value Variable > select the variable you had chosen in the step 3 > OK.
6. Save Mapping.
