  The SAP error message FSBP_FND_INBOUND001 indicates that there is an issue with the relationship category being used in a business partner (BP) context. Specifically, it states that the relationship category you are trying to use supports only one-way relationships, but it appears that a two-way relationship is being attempted.
  Cause:
  This error typically arises when:
  
  You are trying to create or update a relationship between business partners that is defined as one-way, but the system is being instructed to treat it as a two-way relationship.
  The relationship category you are using does not allow for reciprocal relationships, meaning that if Business Partner A is related to Business Partner B, Business Partner B cannot automatically be related back to Business Partner A using the same relationship category.

  Check Relationship Category: Review the relationship category you are using. Ensure that it is indeed a one-way relationship. You can do this by navigating to the configuration settings for business partner relationships in your SAP system.
  
  
  Adjust Relationship Type: If you need a two-way relationship, you may need to select a different relationship category that supports two-way relationships. Alternatively, you can create a separate relationship entry for the reverse direction.
  
  
  Review Data Input: Ensure that the data being inputted for the relationship is correct and adheres to the constraints of the relationship category. This includes checking the directionality of the relationship.
  
  
  Consult Documentation: Refer to the SAP documentation or help resources for specific details on the relationship categories and their constraints. This can provide insights into which categories are one-way and which are two-way.
