Not able to transfer customer from ECC to GTS system, but material master data is OK

Hi Experts,

I'm trying to transfer the customer master data form ECC to GTS stsstem, but got the error message "Of 4 selected partner(s), 0 were processed successfully". I check the result of RFC and ABAP runtime error in ECC site , nothing is generated. I check the Logs in GTS site, no logs can be found. But for the material master data, everything is OK. I'v checked the configuration in both sites.

ECC site:

Use program: /SAPSLL/PLUGIN_CHECK_R3

GTS site:

Does anybody has an idea? Thanks to all for the possible help.

Thanks very much in advance.
