thanks for replying me.. but how can i delete it, when i delete it on the system it also throws the same error..

Records should be deleted from last to first. In this case there is nothing to recompute.
Also If you have a problem with RecursionError, it means you have a lot statements to delete. It will be better to do this from shell.

Or you can try to increase python recursion limit.

yes yes, yesterday i just delete the datas with sql query but still got the error and i think the second solution might solve the problem, is the thing that i need to do is import module sys from python and directly edit sys.setrecursionlimit from python file in models directory in module odoo?? did you have any reference? thanks..

To modify Odoo data with raw SQL request it is bad idea. You should use model methods to change model data.

To change interpreter stack limit you should in any your odoo module, in any python file (for example "__init__.py")) insert 2 strings:
```
from sys import setrecursionlimit
setrecursionlimit(some_value_more_than_1000)
```

alright, it works! but i want to know is there a consequence if we extend the limit of recursion in odoo? thanks a lot man, really appreciate it

If your new limit will be more than your system can handle, you can get C's StackOverflowException.

do you have any reference for me to calculate things between max limit recursion and my system capabilities?

I haven't, sorry.
I just can to recomend set this parameter at lowest value allowing to solve your problem. It should be far away from system limits.

it's okay.. thanks again anyway mate, i will pray for your success for helping me

Someone I know encountered the same issue when closing pos session, with really big database (~60 GB). I think it is worth mentioning that if you increase the recursion limit, you must also increase the stack memory size, to avoid stackoverflow errors. see this https://stackoverflow.com/a/16248113/3557761
