Failed to save modifications to the server. Error returned: "There's not enough memory

[vbis]

Hello. 

I would need your help please with the error I am getting when i try to apply my changes in my desktop power bi.

Failed to save modifications to the server. Error returned: "There's not enough memory to complete this operation. Please try again later when there may be more memory avaialble."

Until last month i was able to apply the changes but this time i am not. I only uploaded the data for the month of November and when i clicked close and apply i got this error. 

The size of the dashboard is not that big (186MB) and i couldn't say that i have many measures created. 

Can you please help me solve this. Soon i will need to uploa the December numbers as well. 

Thank you.

Hi @vbis 

When you apply the changes, it will query data from the data source and load data into the model. When you are using Power BI Desktop, the model is hosted in the active memory of your computer so the data is also loaded into the computer's memory. The transformation and DAX calculation also need to consume additional memory. This error usually occurs when there is no available memory for it.

You can launch Task Manager App on your computer and check whether there are some Apps consuming a lot of memory. If some Apps are not necessarily in use currently, you can close them to spare some memory. If possible, you can try using a computer which has a larger memory size. 

If above methods don't help, you may need to optimize the data model and calculations. Remove unnecessary data to reduce the data size and optimize the complex data transformations/calculations.
