1. Open configuration activity 101016 "Define Tax Codes for Sales and Purchases".
2. Enter the country/region and the affected tax code, then continue.
3. On the tax code details, attempt to use "Deactivate Line" for one of the tax condition lines.
4. Observe that error FOT_COMMON014 "Deactivation only possible for tax codes with one period" is raised.
5. On the tax code details, attempt to use "Delete Last Rate Change" for the same tax condition line.
6. Observe that error FOT_COMMON013 "Undo is not possible with only one period" is raised.

In configuration activity 103887 - Message Control in Tax Area, the error message FOT_TDT/074 "Valid from date of tax code &1 is before valid from date in customizing" has been maintained as a warning message beforehand. This allows inconsistent entries (misaligned valid-from dates) that lead to multiple periods and prevent standard deactivation.

Overwrite the inconsistent entries by following the below steps:

1. In configuration activity 101016 "Define Tax Codes for Sales and Purchases", check the "valid from" date (01.01.2025) of the affected tax code.

2. For the detected "valid from" date in step 1 (01.01.2025), maintain the appropriate percentage rates so that related conditions (for example, input and output tax conditions such as NLXA and NLXV) are consistent and share the same valid-from date. At this point, all active conditions should have the same valid from date and only one period. 

3. Go back to the original "valid from" date (01.01.2026), "Deactivate Line" for the unnecessary conditions as normal

***Important***

In configuration activity 103887 "Message Control in Tax Area", set message FOT_TDT/074 back to Error Message type "E" (not "W") to prevent future inconsistencies.
