Hello CMS, I am unable to get past the following error (suite id u-dg192). > Error code: 6 > [0] ? Error from routine: UM\_READDUMP > [0] ? Error message: UM\_READDUMP Dump does not match STASH list: Wrong processing code. > [0] ? Error from processor: 80 > [0] ? Error number: 64 I have referred to this earlier post and solution by Ella @shakka → [UM\_READDUMP STASH processing code error](https://cms-helpdesk.ncas.ac.uk/t/um-readdump-stash-processing-code-error/1097) These are the things I have tried based on her post: - Running the tidystashtransform macro - Tried removing and re-adding them and _not_ running the macro, as suggested by Paul Field. These steps don’t help. If I disable this STASH- the model runs fine. Please advice. Should I be removing all the STASH and add them manually again- a very cumbersome task. Best Wishes Sid ---

Sid 0 409 is a prognostic but the model does not include that prognostic. Try adding item 222 from section 16 instead. Grenville ---

Hello Grenville Thanks for that suggestion. I am dumping pressure at theta levels, so might just extract the lowest level data assuming it to be the surface level fields. That’s still 5 m AGL, so not much of an error expected. 16, 222 would be Pressure @MSL and may not be a good STASH over orographic regions which I am dealing with rn, so may have to disable 0, 409 to keep the model going. Many thanks Sid ---
