when I have uqdate the item data_type and uqload the CRF,it will have a issue
I had entered data in my CRF,and then I I have uqdate data_type in the CRF and uqload the CRF,so it have some issue,like this:
You may not modify the Description, Data Type, Units, or PHI Status of items already included in this CRF.
The item 'MRI_AB' in your spreadsheet already
exists for this CRF (as part of another version) and has a different
DESCRIPTION(Describe Results), DATA_TYPE(st), UNITS(), and/or
PHI_STATUS(false). These fields cannot be modified, and if you continue, the PHI, UNITS, DESCRIPTION, and/or
DATA_TYPE for this item will be ignored. If you do wish to keep your
settings, please go back and rename the item to one that does not
already exist in the CRF.
what can I do if I meet this issue?
