Sub catergory not defined error

I get an error SUBCATEGORY_V1:869 not found when I open database.
What is it and how to fix?

try this
viewtopic.php?f=16&t=5552

then use transaction report to find invalid transactins then edit it.

SQL may be executed as is ur as report in mmex 1.1.0

Sorry but though I have programmed various languages in past not sure how to use the information supplied.
