"Start constraint not permitted for summary task".


SAP Business ByDesign

Reproducing the Issue

  1. Go to Business Configuration-> Overview
  2. Select Migration of Projects activity
  3. Select Migrate projects using the migration tool 
  4. Select the file
  5. Execute step by step
  6. Error appears. 


The issue occurs due to the mapping that is provided in step "Convert Values". There you can see that the start constraint type 1 is mapped to value X (X refers to any other number than 1).

When we attempt to create the project, we add the project summary task which gets the start constraint type 1. But due to the provided mapping, it is set to X which is a forbidden value for the project summary task.

Additionally, ensure that when the project is created, the given dates in the expenses, tasks must be in the range of the project start date and end date.


Please change the mapping so that start constraint value 1 is mapped to value 1 and ensure that the start and end dates are correctly maintained w.r.t project start and end date. Once this is done, you can upload your project via migration tool.
