Azuretable.PullAsync() not syncing all records from azure db to local SQLite db.

Question

Hi All,
I am developing a Windows store app (WinRT 8.1) where I am implementing offline capabilities using azure mobile services.
When I am syncing the data from azure to local SQLite, some records not syncing even though the data exist in that table... I cross checked my code and the query to filter the records, everything is fine from backend code. But I am not able
to figure out the issue, why some are syncing and some are not syncing.
The below mentioned is the code I am using to sync the table data from azure
var devicesList = await deviceTbl.ToCollectionAsync();
foreach (var device in devicesList)
var pItems = await planogram_ItemTbl.Where(x => x.DEVICE_ID == device.DEVICE_ID).ToCollectionAsync();
foreach (var pItem in pItems)
await productTbl.PullAsync("ProductSync_Table", productTbl.Where(x => x.Id == pItem.productGUID));
I want to sync only the data from product table based on the pItems I have, Is this way is correct ...
Can anyone suggest me how to pull the records based on the another table records...
With this approach I have sync problems, some records are not syncing and it is taking more time.

Here are a few questions for you.
1) Do you get any errors reported?
2) Is "ProductSync_Table" the same name of the table in your Mobile services database?
Rather than going through a loop to Pull the data, you can try something like below:
var newItems = pItems.Select(pItem => pItem.productGUID).ToList();
await productTbl.PullAsync("ProductSync_Table", productTbl.Where(x => newItems.Contains(x.Id)));
I haven't tested the code but something like above should help.
Let me know if that helps.
