How to Control Data upload in 0cordmode

 

There are four recordmode types: A, X, R, and null. These four types are stored in PSA and uploaded to DSO, but not all DSO are stored, the operation is based on the user's operations (ADD, modify, delete.

Here I want to explain the DSO processing methods for these three operations. Of course, this is my own understanding. If there is anything wrong, please instruct me. Thank you very much .....

NewA credential transmits an n to PSA. N indicates "new" and is inserted to DSO. DSO and cube share the same record.

DeleteIf a credential is uploaded to PSA by R, R indicates "delete". It is only a data upload. To DSO, the original data will be deleted, and then DSO will be transferred to cube as a negative one;

ModifyA credential transmits an X and an empty image to PSA. X indicates the mirror image, that is, what it looks like before, and null indicates the modified image. After DSO, X will delete the original data and leave the blank one. If DSO uploads data to the Cube, it will upload the original negative one and the current one.
