GI reversal qty can not exceeding GI qty

Hi, I've uploaded goods movement type 261 using ZPP_UPLOAD_GI_GR_PRO and the status is success.

However when I tried to upload for 262 for only 1 material part, it says "GI reversal qty can not exceeding GI qty".
When I went to check on the PRO's documented good movement, that 1 material part was uploaded 261 = 170 pcs

262 to be uploaded was 170 pcs as well.

It shouldn't exceed, so please let me know if there's any wrong step?

Thank you
