Issues with Model Cardinality in Webdynpro project


Hi experts,

We are working in NWDS 7.1 EHP1

I have a webdynpro project which is using a model. This model is a Service Interface (DEBMAS06) which is published in ESR.

This webdynpro fills data in this model and trigger a new DEBMAS06 idoc to ECC.

I've changed the idoc in ECC to have this new z extension in the idoc. It has been reimported in ESR, reimported the model successfully in my project, changed accordingly the context and the source code but when filling the idoc i get the following error and idoc is not created:

java.lang.IllegalArgumentException: Cannot perform operation 'getRelatedModelObject' for multiple target role 'IDOC' of model class 'com.bacardi.localdatapostmodel.ZDEBMAS06' with cardinality 'MANY'

Any idea how to solve this issue?

Thanks in advance
