Issue/Introduction

When adding an element, why am I getting an allocation error:
 

C1E0116E  RC=0210-0000 ALLOCATION ERROR  - iprfx.iqual.BASE                                                
C1G0268E  ELEMENT RECORD WAS NOT FOUND FOR ELEMENT IN ENV: ENV1 SYS: TEST SBS: TEST STAGE 1                    
C1G0277I  ADD PROCESSING TERMINATED BECAUSE OF THE PREVIOUS ERROR                                               
C1G0200I  ELEMENT ACTION REQUEST PROCESSING COMPLETED, HIGHEST ENDEVOR RC WAS 0012                              
                     END OF EXECUTION LOG - HIGHEST ENDEVOR RC = 0012                                              

Resolution

The return code RC=0210-0000 indicates the dataset was not available to Endevor and another task had an exclusive enqueue on file. Check for tasks that may have hold on dataset.
