When I added 6 individual filters in the configuration:

And run it:

Add first step is OK, but when select Year 2016 and add second step, dump occurred:

The error is “Filter condition is too complex”

The batch request URL is as below:

Seems indeed it’s very complex… but all the filters are necessary, looks like I have to try Smart Filter instead…

I’ve copied the configuration, you could use the copied one:

我找到了具体引起这个错误的ABAP code，一会给你说怎么定位：

现在在看怎么避免这个error。你第一次添加step时能够正常工作，因为it_filter_select_options和iv_filter_string都是有值的：

而添加第二个step时，it_filter_select_options不知为何为空了，所以框架检查出错：

还需要继续看。第一个step传到后台的url:

解析出错的原因
这个BILLINGDOCUMENTDATEYEAR出现在了一个内表里，expect的行为是不出现。还需要看。

比较两个step发送url有何差异，已经能看出原因了，蓝色的区域是第二个step新增加的url:

之前的研究概括起来就是：在第一个step的chart上选中2016年那个节点，然后创建第二个step，此时给后台发送的url如下：

这时选中的context 2016年就是上图紫色的内容，通过debug框架，发现其验证逻辑认为紫色的2016年是不合法的，因为and 左边的filter里已经包含了这个条件了，所以报错。这些url都是APF runtime 负责拼接再传给后台的，我们没办法控制，这个问题可能需要和APF的同事一起来看：
或者是我们filter的modelling有问题
或者是APF 处理filter这块的JS代码有问题

We got this “filter condition is too complex error” again, add sap-apf-filter-reduction=true in the URL doesn’t work this time.
Go to:

https://jerry.wdf.sap.corp:1300/sap/bc/ui5_ui5/ui2/ushell/shells/abap/FioriLaunchpad.html?sap-client=928#BillingDocument-testSalesVolume?EvaluationId=.E.1464769533103&sap-xapp-state=ASMUJD92Q3C7JZ6BJ9G5AA8DNIVBC7IKQFPAM4WD&/
Don’t change filter, add a step, the error will occur.

I checked the error log and debugged the code like we did last time, I found that the cause is not the same as the last time:
Filter check code on ER9:

It seems the code check if there’re more than one filters have more than one values in the condition, if so, it will raise error.
