CI for Requisition Component throwing error

Hi,

I am working on a Rest service in which I am reading data from JSON file. I am parsing data and putting them into records created as copy of REQ_HDR, REQ_LINE, REQ_LINE_SHIP and REQ_DIST_LINE. Now I am looping into these records and putting the value in respective collection of CI. I have not created the CI with Default properties but instead pull the collections for above record with REQ_LINE_WRK and ITM_CAT_WRK.

I am getting the below error while saving the component.

(15,54) - The field {BC_SCM_REQUISITION_2.REQ_LINE(1).CATEGORY_ID} is required.  You must enter a value for it before proceeding. (15,54)
