In addition to the possible causes suggested in our earlier post “Understanding the NSc Sync E1350 and E1351 Error Codes” the problem may also be due to the absence of unique IDs in your SEO URL formats.
Try adding unique IDs to the formats for the product, department, and category SEO URLs
To circumvent this issue, we recommend the following SEO URL formats:
- Product: /%product_name%-%product_code%-%product_id%/
- Department: /%department_name%-%department_id%/
- Category: /%department_name%-%category_name%-%department_id%-%category_id%/
