Item sync did not work because of similar SKU exists

Item sync did not work because of similar SKU exists

Hello,

I initiated a manual item fetch from shopify to zoho inventory but majority of the items did not sync. 

Majority of the errors are showing the following error- "SKU already exists".

The items were previously created in Zoho and shopify manually using the same SKU, but they were not mapped for auto fetch. 

Now that I initiated an item fetch, it showed the below errors. Let me know how to fix this.
