• What is the cause and solution for SAP error message AQ158 - Maximum 99 info types allowed ?

  The SAP error message AQ158 "Maximum 99 info types allowed" typically occurs when you are trying to create or manage infotypes in the SAP system, and you have exceeded the limit of 99 infotypes that can be assigned to a particular object or record.
  Cause:
  
  Exceeding Infotype Limit: The primary cause of this error is that the system has a hard limit of 99 infotypes for certain objects (like personnel records in HR). If you attempt to add or modify an infotype that would exceed this limit, the error will be triggered.
  Configuration Issues: Sometimes, the configuration of the infotypes or the way they are being used in the system can lead to this error.
  
  Solution:
  
  Review Infotypes: Check the infotypes that are currently assigned to the object in question. You can do this by navigating to the relevant transaction (like PA20 for displaying HR master data) and reviewing the infotypes.
  Remove Unused Infotypes: If there are infotypes that are no longer needed, consider removing them to free up space for new infotypes.
  Consolidate Data: If possible, consolidate the data from multiple infotypes into fewer infotypes. This may involve re-evaluating how data is structured and stored.
  Custom Development: If your business requirements necessitate more than 99 infotypes, you may need to consider custom development or alternative approaches to manage the data without exceeding the limit.
  Consult Documentation: Review SAP documentation or consult with your SAP support team for best practices regarding infotype management.
  
  Related Information:
  
  Infotypes: Infotypes are data structures in SAP that store specific types of information related to an object (like employee data in HR).
  SAP HR Module: This error is commonly encountered in the SAP Human Resources (HR) module, where infotypes are heavily utilized to manage employee data.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as PA30 (Maintain HR Master Data), PA20 (Display HR Master Data), and others that may help in managing infotypes.
  
  If the issue persists after trying the above solutions, it may be beneficial to reach out to your SAP support team or consult SAP Notes for any specific patches or updates related to this error.
