Problem with my Calculated Field dan Calculated Geometry

[sansan333]

I'm having trouble for calculating attributes. Why my field calculator and calculated geometry doesn't work (disable) in my ArcGIS Pro? I've been updated to the latest version, but it still doesn't work. Any suggestions? Please help. Thanks

what is the type and source of the featureclass that you are trying to do calculations on?

is it a featureclass?  locally stored?  do you own it or have permissions to edit it?  is the table joined?

there are other reasons but you need to clarify your situation

Try these checks—each one can cause Field Calculator / Calculate Field / Calculate Geometry Attributes to be disabled in ArcGIS Pro:

Confirm the layer is editable

In the Contents pane, switch to List By Editing and make sure the layer is checked (editable).
Ref: Problem: The Calculate and Calculate Field options are disabled in ArcGIS Pro

Make sure you’re calculating a supported field

Calculate Geometry Attributes only enables for certain field types (short/long/double/float/big integer/text) and not for system fields (OBJECTID, Shape, Shape_Length, Shape_Area).
Ref: Problem: The Calculate Geometry option is disabled in ArcGIS Pro

Check the field isn’t set to Read Only

Open the layer’s Fields view and uncheck Read Only for the target field, then Save.

If it’s a feature service, don’t run Calculate Field in an edit session

The geoprocessing Calculate Field tool can be blocked for feature services when you’re in an edit session / Enable Undo is on (unless using a supported branch-versioned workflow).
Ref: 003307: Calculate Field is not supported against a feature service within an edit session

Verify coordinate system isn’t “Unknown”

If the map/dataset has an unknown coordinate system, calculate options may be disabled.

Repair geometry (for Calculate Geometry being disabled)

Run Repair Geometry on the feature class.
